如何使用jQuery获取父元素值？

Question

我有一个表，有两行，每行有两个单元格，每个单元格有几个信息，如办公室名称，地址和电话号码等。每个jQuery使用jquery，地址从每个单元格中拉出并馈送进入谷歌地图地理编码器对象以获取该点并将其绘制在地图中。现在，在地址值的每次命中时，我还想从jquery获取地址值的当前单元格中获取手机和办公室名称的唯一值。我需要这些值，以便我可以在InfoWindow中显示这些值地图？我如何获得这些值？

Answer 1

取决于this当前背景下，那么这应该工作：

$(this).parent().find('.officeName').html(); 

Answer 2

$(this).parent().find(".OfficeName").text()获取办公室的名称和$(this).parent().find(".Phone").text()获取手机的每个地址。

jsfiddle - 点击一个地址，它会显示名称和电话的警报。

Answer 3

$('td.Office1').chilldren('.Phone') 

会得到你的办公室1的电话号码从Office 1 TD

$('span.Address').siblings('.Phone') 

会得到你的电话号码与地址跨越

Answer 4

$(this).siblings('.Phone').html()和$(this).siblings('.Address').html()

Answer 6

我们可以通过使用jquery或Javascript来做到这一点。这里我们将讨论电子邮件ID更新。

在波纹管示例中，弹出式窗口将从父窗口自动填充电子邮件ID打开。 更新后，电子邮件会自动在父窗口文本框中更新，并弹出窗口将专门关闭。

例子：

1）创建index.html文件为父窗口

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”> 
<html> 
<title></title> 
<head></head> 

<body> 
<table> 

<tr> 
<td colspan=”2″>Example for update email id.</td> 
</tr> 
<tr> 
<td>Email Id:</td> 
<td> 
<input type=’text’ name=”emailID” id=”emailId” value=”demo@demo.com”></td> 
</tr> 
<tr> 
<td> 
<input type=”button” name=”update” value=”Update” 
onClick=’window.open(“update_popup.html”, “”, “width=400, height=300″)’> 
</td> 
</tr> 
</table> 
</body> 
</html> 

2）创建为弹出窗口，电子邮件ID自动从填文件update_popup.html父窗口进行更新。

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”> 
<html> 
<title></title> 
<head></head> 
<script src=”http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js”></script> 
<script> 
$(document).ready(function(){ 

//== pre fill parent window email id in popup window for update 

var emailId = window.opener.document.getElementById(“emailId”).value; 
$(“#emailId”).val(emailId); 

//=== update updated email id in to parent window 

$(“#Save”).on(‘click’,function(){ 

var updated_emailId = $(“#emailId”).val(); 
window.opener.document.getElementById(“emailId”).value = updated_emailId; 
window.close(); 
}); 
}); 
</script> 

<body> 
<table> 
<tr> 
<td>Email Id:</td> 
<td> 
<input type=’text’ name=”emailID” id=”emailId” value=””></td> 
</tr> 
<tr> 
<td><input type=”button” name=”Save” id=”Save” value=”Save”></td> 
</tr> 
</table> 
</body> 
</html>
